One case, three components
A portable power station is only useful if it is light enough to carry and honest about what it can run. Integrating the inverter, BMS and battery in one enclosure removes the DC wiring, the breaker and the compatibility question that come with a separate battery and inverter.
This series covers the range from a 300 W weekend unit to an 1800 W mobile pack with 4 kWh, in five mechanical variants: the standard box, a Type-C fast-charging version with LED lighting, an ultra-slim wall-mounted unit, a trolley-mounted mobile version, and a US-standard 110 V range.
Sizing a portable system
The number that matters is watt-hours at the load, not nameplate capacity. A 1 kWh pack delivers roughly 850 Wh usable at 85 % depth of discharge — enough for a 60 W fridge cycling at 50 % duty for about 28 hours, or a laptop for a working week.
Surge is the second number. A 1000 W unit starting a 900 W angle grinder needs the peak rating to hold for a second or more; check the peak figure for the model, not the series.

Applications
Camping and outdoor work
Runs a fridge, lights, laptop and power tools from a 1 kWh pack that fits in a car boot.
Emergency backup
Keeps a router, phone charging and a lamp running through an outage, and recharges from a car or a solar panel.
Cabins and kiosks
The wall-mounted variant powers lights, a fan and a phone charger where there is no grid connection.
FAQ
Can it be charged from a solar panel?
Yes — the PV input takes a standard panel within the model's voltage window. A 200–400 W folding panel charges the 1 kWh units in about three hours of good sun.
What can a 1000 W unit run?
A fridge, lights, a laptop and a fan simultaneously, or a 900 W power tool on its own. Resistive loads are easy; motors need the surge rating checked.
Does it support pass-through charging?
Yes — charge from the mains or solar while supplying a load. On models with a UPS-mode output the transfer is automatic.
How long do the cells last?
LiFePO4 cells rated at up to 8,000 cycles. At one full cycle a day that is well over a decade; in camping use, considerably longer.
